Kirschbaum Flash 1.30 mm is a co-polyester tennis string designed for players who want a lively response, reliable durability, and control when hitting with pace. Its textured surface helps support spin production, while the softer feel for a polyester string makes it an option for players seeking a more comfortable response without giving up a controlled playing style.
Players with medium-to-fast swings who want a durable polyester string for aggressive groundstrokes, spin-friendly shot-making, and confident control. Its 1.30 mm gauge is suited to players who prioritize durability over the livelier response often associated with thinner strings.
